Her brain chemistry has been severely altered.
Its now a question of: Is there a way to eliminate these powers and get Caitlin back?
Is there a way to get Caitlin back and leave her with these powers?

What is Cisco [Carlos Valdes] willing to do to save his best friend?
What is Julian [Tom Felton] willing to do to save the woman he loves?
Suffice it to say, Killer Frost wont go down without a fight.
Now that Killer Frost is free, I dont think shes interested in going away nicely.
Killer Frosts quick alignment with Savitar informs a lot of the decisions that she makes.
How lost is Caitlin that shes willing to do what Savitar needs her to do?
She plays a unique part.
Hes not just looking for an evil cohort; shes actually necessary for him to pull off his plans.
I really like that it took Caitlin Snow a long time to warm up to Julian, Panabaker says.
Her initial instinct to bring him to Team Flash, she didnt look at him as a romantic interest.
I dont know what their future looks like.
Its just going to be this struggle of Caitlin Snow vs. Killer Frost, whos going to win out?
Killer Frosts increased presence will make for a powerful quite literally finale.
Its going to be great, Panabaker says.
From a totally biased perspective, its great to see a lot more of the familiar faces.
Im enjoying getting to play her.
Obviously Danielle Panabaker is not going anywhere, Kreisberg adds.
The things Caitlin remembers, Killer Frost can access as well.
Its more a question of if she chooses to and how she feels about Caitlins memories.
